Subject: [PATCH 10/12] riscv: add gpr-num.h
Date: Thu, 18 Nov 2021 19:26:29 +0800 [thread overview]
Message-ID: <20211118192629.0a9dc6ad@xhacker> (raw)
In-Reply-To: <20211118192130.48b8f04c@xhacker>
From: Jisheng Zhang <jszhang@kernel.org>
Next patch will use the gpr-num to pass the register number to exception
fixup handler which sits in inline assembly routines.
